Analysis of Neutron Scattering in Fast Neutron Imaging

  • 摘要: 通过一内空的圆柱体模型,对在快中子照相时由样品引起的散射中子强度与样品形状和探测距离之间的关系进行模拟,并用^241Am—Be作中子源对散射中子的影响进行实验验证。结果表明,在快中子照相时,由样品引起的散射中子的强度与探测距离以及样品形状有关。对于同一样品,探测距离增加,散射中子的影响则降低。The relationships between intensities of scattered neutrons by specimens and their shapes and detecting distances have been simulated using a hollow cylinder model, and the results were validated by experiments of fast neutron imaging using ^241Am-Be neutron source. The results showed that the intensities of scattered neutrons are closely related to the detecting distances and sample' s shapes. The influences of scattered neutronns in fast neutron imaging will be reduced while detecting distances increased.
